CROSS REFERENCE TO RELATED APPLICATIONS

This application claims benefit to provisional application 60/751,088, filed on Dec. 16, 2005, entitled “Sleep System with Purified Air and Latex Foam Mattress”, which is incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

The present invention is directed to the field of sleep systems. In particular, the present invention incorporates purified air with the comfort of a natural latex foam mattress.

BACKGROUND OF THE INVENTION

Issues involving sleep depravation have recently come into the public's awareness. Recent studies by the American Medical Association have shown sleep deprivation is a major cause of a wide range of illnesses including heart disease and hypertension. One particular problem is that people often do not breathe properly when sleeping and do not breathe fresh air, particularly when they are face down or lying sideways in the bed. When the body heat elevates, the heartrate starts to elevate to sweat. A cooler area is preferable.

A number of patents have issued in the area of systems for improving sleeping or for providing improved mattresses. U.S. Pat. No. 6,484,340 discloses a mattress core made from foamed material, latex, or plastic being provided with a series of hollow spaces running perpendicular to its longitudinal axis. According to the invention, it is provided that coil springs are positioned in a lying fashion in the hollow spaces running perpendicularly to the longitudinal axis of the foam core. Preferably, the coil springs are produced from a tape material and a fibrous composition material and foamed in.

U.S. Pat. No. 5,850,648 discloses an anatomical mattress comprising at least two layers of elastic material each having a main surface. The elastic layers are joined along the main surfaces thereof to define a generally parallelepiped-shaped body. The body has a peripheral frame and two opposite surfaces. At least a portion of one of the opposite surfaces of the body has semispherical-shaped elements extending outwardly therefrom and defining a lying plane of the mattress. At least two transverse reinforcing and stiffening bands are disposed in the body at positions corresponding generally with the shoulders and feet, respectively, of a user.

U.S. Pat. No. 6,684,433 discloses a pressure adjustable foam support apparatus includes a resilient, air pressure adjustable, self-inflating foam core. A flexible, airtight cover encloses the core. One or more air passageways are formed through the covering in pneumatic communication with the foam core. Each passageway carries a valve for alternately permitting and blocking passage into and out of the core through the passageway. The valve is opened to exhaust air from and at least partially collapse the core and to allow a core that is at least partially collapsed to draw in air through the passageway and expand. The valve is closed to maintain a selected air pressure within the core whereby corresponding levels of density and firmness (IFD) are exhibited by the core. At least one level of density and firmness provides the core with a viscoelastic or latex foam feel hence greatly reducing pressure points and increasing comfort. A pressure adjustable foam support apparatus that can be made into a mattress, sofa bed, hospital mattress, futon mattress, couch, chaise lounge cushion, mattress topper and other furniture.

U.S. Pat. No. 5,325,551 discloses a mattress unit for retarding the development of decubitus ulcers includes a fabric cover having therein a foam material, and includes an inflatable bladder and a control unit disposed within openings in the foam material. The inflatable bladder contains a foam material having spaced holes in it. The control unit includes a pump which can selectively supply pressurized air to the bladder, a valve which can selectively bleed air from the bladder, and a pressure sensor which can determine the current pressure in the bladder. The pressure sensor is coupled to an input of a control circuit which controls the pump and valve. The control circuit receives power from an AC/DC converter and is remotely controlled by a hand-held pendant, the converter and pendant each being physically separate from the mattress unit and being connected to the control circuit by respective cables.

U.S. Patent Application No. 2002148045 discloses a pressure adjustable foam support apparatus includes a resilient, air pressure adjustable, self-inflating foam core. A flexible, airtight cover encloses the core. One or more air passageways are formed through the covering in pneumatic communication with the foam core. Each passageway carries a valve for alternately permitting and blocking passage into and out of the core through the passageway. The valve is opened to exhaust air from and at least partially collapse the core and to allow a core that is at least partially collapsed to draw in air through the passageway and expand. The valve is closed to maintain a selected air pressure within the core whereby corresponding levels of density and firmness (IFD) are exhibited by the core. At least one level of density and firmness provides the core with a viscoelastic or latex foam feel hence greatly reducing pressure points and increasing comfort. A pressure adjustable foam support apparatus that can be made into a mattress, sofa bed, hospital mattress, futon mattress, couch, chaise lounge cushion, mattress topper and other furniture.

U.S. Patent Application No. 20020015817 discloses a quilted pad is made by chopping post-industrial scrap foam into particles and blowing the chopped particles into an air cyclone. The cyclone separates the particles from the air stream and feeds them into a foam layout machine. The chopped foam particles are deposited across a fabric bottom carrier sheet in a uniform layer. A multi-needle quilting machine lays a top fabric sheet across the foam layer, and then quilts a geometric pattern of pockets which separate and secure the foam particles. The foam particle sheet is then cut into panels and the panel edges are finished, creating a low cost but highly functional and attractive pad that can be used as a cushioning pad internal to a conventional bed mattress, as padding in the manufacture of futons, or as a low cost mattresses for camping, for use in emergency and homeless shelters.

U.S. Patent Application No. 20050005364 discloses a stiffening system for the perimeter edges of a foam core mattress comprising a coil spring (or other spring-based) structure disposed along one or more perimeter edges (e.g., one or both side edges, the foot, the head, or a combinations thereof including the foot and both side edges) of a mattress having a foam sleeping area. The perimeter spring structure is rectangular or square in cross-section and provides sufficient stiffness for comfortable seating on the edges of the mattress and is joined to the foam core by planar fabric elements that span the joint between them and are attached to both. The sleep area provides the softness and other salutary effects of a foam sleeping surface while the stiffer spring perimeter element provides the rigidity need for comfortable seating and wear resistance.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The invention is directed towards a sleep system that incorporates purified air with the comfort of natural latex foam. Referring to FIGS. 1-5, the present invention is described. The present invention is broadly directed to a mattress system in which purified air is pumped into a mattress.

The invention 10 comprises a number of base components. The system initially comprises a base 12 for supporting the mattress system in a horizontal position. The base encases an air purification device 14. The device may include a pump and filter, including a HEPA filter. Air filtration systems of this type are well known in the art. The filtration pump is connected to a plurality of hoses 16. The hoses 16 then connect to the underside of a platform 20.

The platform 20 is rectangular in shape and has a bottom rectangular surface 22, side walls 23 and a top rectangular surface 24. The sidewalls create an air packet between the first and second surfaces. The bottom rectangular surface is solid except for four access ports 26. The ports are attached to the hoses 16 from the pump 12.

The top rectangular surface has a plurality of small air holes 18. The air space created by the side walls may be further divided into sectors 30 a-30 d, in which each sector is associated with an access port 20.

In a second embodiment shown in FIG. 1 a, the hose 16 enters the platform through the end of the platform.

The mattress 18 is preferably constructed from hypoallergenic all natural latex foam. The foam may be poured into a mold creating approximately ⅜^(th) inch size holes over the entire surface of the mattress and through the top and bottom.

The mattress 12 lies on top of the platform. The latex mattress has holes to allow air to pass from the platform 20 through the mattress and on to the end user. The platform contains four separate chambers 12 and each chamber connects to a plastic hose 14. The hoses 14 connect to an air purification system 14 that cleans and filters the air and sends it through the holes in the bed generating breeze of cool, purified air. The cool air assists in maintaining a cool temperature for the sleeper.

An alternative embodiment of the invention is shown in FIGS. 1 b, 4 and 5. In FIG. 1 b, air holes enter at two ends of the platform, instead of through the bottom. FIGS. 4 and 5 illustrate yet another embodiment. Here, the air hoses attach to openings 24 at one end of the platform 20. The air passes through a plurality of holes onto the mattress. The lower portion of the purification unit 14 sucks in dry air and purified, filtered air leaves the hoses 16.

All cool filtered embodiments of the invention provide air which keeps the sleeper cool and thus reduces the heart rate of the sleeper.
